Lorawan Intialization error

Setting up RAK7431 on the Helium network. After entering the Devui appui appkey via the AT commands. When AT+restart. I receive error SYSLOG:1:ERROR:LORAWAN Initialization ERROR. My assumption is it cant see the Gateway ie:Helium Hotspot on my roof. I do have another device that see’s it fine from Dragino. The Dragino came with devui etc written on the box. Any suggestions for RAK7431 also made sure using OTAA and US915
